A Real Estate Investment Trust files IRS Form 1120-REIT every year to report income, claim the dividends-paid deduction, and prove it still qualifies as a REIT under IRC §856. The form keeps the REIT’s pass-through tax treatment alive, which is the entire reason the entity exists.
You file it by the 15th day of the 4th month after your tax year ends, which is April 15 for calendar-year REITs, with a six-month extension available through Form 7004. Miss a test or a line, and the IRS can revoke REIT status for five years under the rules in IRC §856(g).
According to the Nareit T-Tracker, U.S. listed REITs paid out roughly $79.5 billion in dividends in 2024, and every dollar of that flowed through a Form 1120-REIT.

What Form 1120-REIT Is and Who Must File It
Form 1120-REIT is the federal income tax return for any domestic corporation, trust, or association that elects REIT status under IRC §856(c)(1). The election is made by simply filing the form for the first tax year the entity wants REIT treatment, per the Form 1120-REIT instructions. The IRS treats the first timely filing as the election itself, so there is no separate election form.
Every entity that has elected REIT status must file, even if it has no taxable income, no shareholders other than the sponsor, or operating losses for the year. The duty to file does not pause when income drops to zero, because the qualification tests still run on whatever income exists. A REIT that skips a year of filing risks an automatic termination of its election under Treas. Reg. §1.856-2.
The form covers equity REITs that hold real property, mortgage REITs that hold loans secured by real property, and hybrid REITs that hold both. It also covers publicly traded REITs, public non-listed REITs, and private REITs, since the Internal Revenue Code does not separate them for tax purposes. The 100-shareholder rule in IRC §856(a)(5) and the five-or-fewer rule in IRC §856(h) still apply across all three flavors.
A taxable REIT subsidiary, called a TRS, does not file Form 1120-REIT. A TRS files a regular Form 1120 and pays full corporate tax at 21% on its own income, as required by IRC §856(l). The parent REIT then reports the dividend it receives from the TRS on its own 1120-REIT.
A common misconception is that REITs pay no tax. They actually pay tax on any income they retain, on prohibited transactions at 100% under IRC §857(b)(6), and on built-in gains during the recognition period after a C-corp conversion. The pass-through benefit only applies to income the REIT actually distributes to shareholders.
When and Where to File Form 1120-REIT
The filing deadline is the 15th day of the 4th month after the close of the tax year, which is April 15 for calendar-year filers and the 15th day of the 4th month after a fiscal year ends for fiscal-year filers. The IRS confirms this in the Form 1120-REIT instructions. A six-month extension is automatic if you file Form 7004 before the original due date and pay the estimated tax owed.
Late filing without reasonable cause triggers a penalty of 5% of unpaid tax per month, up to 25%, under IRC §6651. Late payment adds another 0.5% per month on top of interest. The consequence of ignoring the deadline is not just dollars; persistent late filing can also feed an IRS argument that the entity failed to operate as a REIT.
You file electronically through IRS Modernized e-File, which is mandatory for any REIT filing 10 or more returns of any kind in a year under Treas. Reg. §301.6011-15. Paper filing is allowed only for small REITs that fall below the e-file threshold, and even those mail to the Ogden, Utah service center. A real-world example: Coastline Storage REIT, a private REIT with 12 owners, files electronically because it also files Forms 1099-DIV for each shareholder, pushing it over the 10-return threshold.
A common misconception is that an extension of time to file is also an extension of time to pay. It is not. Maria, the CFO of Bayou Apartments REIT, learned this when her timely Form 7004 saved her late-filing penalty but left a 0.5% per month late-payment penalty running on $410,000 of unpaid tax.
Page 1 of Form 1120-REIT, Line by Line
Page 1 captures identity, income, deductions, and tax. Every line ties to a specific Code section, and a wrong entry on Page 1 is the most common reason the IRS opens a REIT exam, according to the IRS Large Business and International Division.
Header Boxes A Through E
The header asks for the type of REIT (equity, mortgage, or hybrid), the date of incorporation, total assets at year-end, and the box that says this is the initial return, final return, name change, or address change. Box A1 must be checked for an equity REIT under IRC §856(c)(3) and Box A2 for a mortgage REIT.
If you check the wrong box, the IRS computer matches your gross income test results to the wrong asset profile and may issue a CP2000 notice. Real example: Northshore Mortgage REIT mistakenly checked the equity box, and the IRS questioned why 92% of its income was interest, threatening disqualification before counsel corrected the box on an amended return.
A common misconception is that the “total assets” figure in the header is informal. It is the same figure that anchors Schedule L and the 75% asset test, so it must reconcile to the books on the same day each year.
Lines 1 Through 10, Income
Line 1 is dividends, Line 2 is interest, Line 3 is gross rents from real property, Line 4 is gross royalties, Line 5 is net capital gains from Schedule D (Form 1120), Line 6 is net non-capital gains from Form 4797, and Line 7 captures other income such as foreclosure property income. The instructions in the Form 1120-REIT instructions define each.
Rents from real property must meet the definition in IRC §856(d), which excludes rent based on net profits and rent from related parties owning 10% or more. The consequence of misclassifying impermissible rent is failing the 75% income test, which can revoke REIT status unless the cure provisions in IRC §856(c)(6) apply.
A common misconception is that parking, vending, or service income inside a building is automatically rent. It is rent only if the services are “usually or customarily rendered” under Treas. Reg. §1.856-4; otherwise it is impermissible tenant service income and must run through a TRS.
Lines 11 Through 25, Deductions
Deductions cover compensation of officers (Line 12, supported by Form 1125-E if total receipts hit $500,000), salaries (Line 13), repairs (Line 14), bad debts (Line 15), rents paid (Line 16), taxes (Line 17), interest (Line 18, subject to the §163(j) limit), depreciation (Line 20, supported by Form 4562), and other deductions (Line 22).
Line 21b is the dividends-paid deduction, the heart of REIT taxation, claimed under IRC §561 and §857(b)(2)(B). The deduction equals dividends actually paid during the year, plus consent dividends, plus any throwback or spillover dividends declared under §858 before the return is filed. The consequence of under-claiming it is corporate tax at 21%, while over-claiming triggers a deficiency assessment.
A common misconception is that capital gain dividends count separately. They are part of the same dividends-paid deduction but must be designated in writing to shareholders within 30 days of year-end under IRC §857(b)(3)(B) so shareholders can apply the right rate.
Lines 26 Through 36, Tax and Payments
Line 22a applies the 21% corporate tax rate to taxable income, which after the dividends-paid deduction is usually small. Line 25 adds the alternative tax on net capital gains the REIT chose to retain and tax at the entity level under IRC §857(b)(3), so shareholders can later claim the credit on Form 2439.
Line 27 carries the Part III prohibited transactions tax at 100%, Line 28 carries the Part IV failure tax under §856(c)(7), and Line 29 carries excise tax under §4981 for under-distribution. Real example: Pinewood Logistics REIT retained $5 million of long-term gain, paid 21% on Line 25, and its shareholders claimed a pro-rata credit through Form 2439.
A common misconception is that estimated tax payments do not apply because REITs distribute most income. Estimated payments are still required under IRC §6655 on built-in gains, retained gains, TRS-related items, and any prohibited transactions tax expected for the year.
Part II, Part III, and Part IV Taxes
Page 2 holds three special tax computations that exist only for REITs. Each one polices a different qualification rule, and each one has its own line on Page 1.
Part II, Tax on Net Income From Foreclosure Property
Foreclosure property is property the REIT acquires by bidding in or accepting a deed in lieu, under the rules in IRC §856(e). Net income from operating that property after foreclosure is taxed at 21% in Part II, because Congress wanted to avoid letting REITs run active operating businesses tax-free.
The election to treat property as foreclosure property must be made on the return for the year of acquisition, and it lasts up to three years. The consequence of failing to elect is that any non-rental income from the property counts against the 95% and 75% income tests, which can blow the REIT election. Real example: Harbor Retail REIT foreclosed on a strip mall, elected foreclosure property treatment, and shielded the cafeteria operating income from the income tests for three years.
A common misconception is that foreclosure property income is tax-free. It is taxed at the regular 21% corporate rate inside Part II, but it is excluded from the income tests, which is the real benefit.
Part III, Tax on Net Income From Prohibited Transactions
A prohibited transaction is a sale of inventory-type property, often called a “dealer sale,” and the gain is taxed at 100% under IRC §857(b)(6). The rule prevents REITs from acting like merchant builders.
The safe harbor in §857(b)(6)(C) lets a REIT avoid the 100% tax if it holds the property for at least two years, makes limited improvements, and stays under either seven sales for the year or a 10% asset/basis cap. Real example: Crescent Land REIT sold 11 lots in one year and missed the seven-sale ceiling, but it still met the 10% basis safe harbor and avoided the 100% tax.
A common misconception is that the 100% tax is the only consequence. The transaction also can fail the 75% income test if the gain is large, which is a separate disqualification risk.
Part IV, Tax on Failure To Meet Certain Requirements
Part IV imposes a tax on income that violates the 95% or 75% income test when the REIT uses the §856(c)(6) cure. The tax equals the greater of the two test failures multiplied by the ratio of REIT taxable income to gross income, which in practice claws back the benefit of the bad income.
The cure is only available if the failure is due to reasonable cause and not willful neglect, supported by a description attached to the return. Without reasonable cause, the REIT loses status and waits five years to re-elect under §856(g)(3). Real example: Aurora Healthcare REIT received an unexpected management fee that broke the 95% test by 0.4%; it filed the cure schedule, paid the Part IV tax, and kept its status.
A common misconception is that any income test failure can be cured. Only failures with reasonable cause qualify, and even then the REIT must self-identify the failure on the return.
Schedules A, J, K, L, M-1, and M-2
The schedules tie the income statement to the balance sheet and to the qualification tests. Skipping any schedule is grounds for an incomplete return notice from the IRS.
Schedule A, Deduction for Dividends Paid
Schedule A computes the dividends-paid deduction in detail, separating ordinary dividends, capital gain dividends, return-of-capital distributions, and consent dividends. Each category has different shareholder consequences, reported later on Form 1099-DIV.
A consent dividend under IRC §565 lets shareholders agree to be taxed on a deemed distribution without cash actually changing hands, useful when the REIT has phantom income. The consequence of getting Schedule A wrong is a wrong dividends-paid deduction on Page 1 Line 21b. Real example: Sage Office REIT used a consent dividend for $2.1 million of cancellation-of-debt income to keep its 90% distribution requirement satisfied.
A common misconception is that the 90% distribution requirement and the dividends-paid deduction are the same number. The 90% test uses REIT taxable income before the deduction, while the deduction itself can be larger or smaller depending on capital gain dividend designations.
Schedule J, Tax Computation
Schedule J calculates the regular 21% tax, the alternative tax on retained capital gains, and any recapture taxes. It also reflects the §163(j) interest limitation for REITs that did not elect out as a real property trade or business.
Most equity REITs elect out under §163(j)(7)(B), trading the interest deduction limit for slower depreciation under the alternative depreciation system. The consequence of electing out is an irrevocable choice that carries forward forever. A common misconception is that the election is annual; it is permanent.
Schedule K, Other Information
Schedule K asks 25-plus yes/no questions, including ownership questions, foreign account questions, and questions about whether the REIT met the 100-shareholder requirement and the closely-held test. Wrong answers here are perjury risk because the form is signed under penalties of perjury.
The 100-shareholder test must be met for at least 335 days of a 12-month tax year under IRC §856(b)(1), and is waived for the first tax year. The five-or-fewer test bars five or fewer individuals from owning more than 50% of the shares during the last half of the tax year, under §856(h). A common misconception is that look-through rules favor the REIT; in fact, §544 attribution often pulls more shares into the closely-held count.
Schedule L, Balance Sheets
Schedule L shows beginning and ending balance sheets on a tax basis. Real estate, mortgages, cash, and TRS stock all flow into the 75% asset test at the close of each quarter, not just year-end, under IRC §856(c)(4).
The consequence of a mid-year asset test failure is an automatic disqualification unless the REIT cures within 30 days after quarter-end. Real example: Lakeshore Industrial REIT sold a $40 million warehouse on March 30 and held the cash on March 31, pushing securities above 25%; it cured by buying real property within 30 days. A common misconception is that Schedule L is just bookkeeping; it is also the audit trail for asset tests.
Schedules M-1 and M-2, Book-Tax Reconciliation
Schedule M-1 reconciles book net income to taxable income before the dividends-paid deduction, and Schedule M-3 replaces it for REITs with $10 million or more in assets. Schedule M-2 tracks unappropriated retained earnings.
Wrong reconciliations create discrepancies the IRS uses to select returns for audit, per the IRS Internal Revenue Manual. A common misconception is that book depreciation can simply equal tax depreciation; for REITs that elected out of §163(j), tax depreciation under ADS will almost always be slower than book depreciation under GAAP.
The Three Big Qualification Tests
The 75% income test, the 95% income test, and the 75% asset test must all pass for the year, or the REIT relies on a cure under §856(c)(6) or (c)(7).
The 75% Income Test
At least 75% of gross income must come from rents from real property, mortgage interest on real property, gain from the sale of real property held for investment, dividends from other REITs, and a few other narrow categories listed in §856(c)(3). The consequence of falling below 75% without a cure is loss of REIT status for the year and a five-year ban.
Real example: Riverstone Hotel REIT leases all hotels to a TRS through an eligible independent contractor, so the rent it receives is good 75% income even though the underlying business is hotel operations. A common misconception is that hotel income directly is good 75% income; only the rent paid by the TRS to the REIT qualifies.
The 95% Income Test
At least 95% of gross income must come from the 75% list plus dividends, interest, and gain from sale of stock or securities. The 5% leeway lets the REIT earn limited fee or service income without disqualifying.
Real example: Beacon Data Center REIT received a $400,000 cross-connect fee that did not qualify under either test, and stopped at 4.7% of gross income, staying within the 95% allowance. A common misconception is that the 95% test is easier than the 75%; the 75% list is a subset, and many income items pass 95% but fail 75%, which is the more common trap.
The 75% Asset Test
At least 75% of asset value must consist of real estate assets, cash, cash items, government securities, and shares of other REITs, measured at the close of each quarter under §856(c)(4). The 25% basket has internal sub-caps: securities of any one non-government issuer cannot exceed 5%, and TRS stock cannot exceed 20% of total assets.
A REIT that holds more than 10% of the voting power or value of any non-TRS issuer also fails the test. The consequence of failure without a 30-day cure is disqualification. A common misconception is that the test runs only at year-end; it runs every quarter, which is why Schedule L data must be supportable on four dates.
Three Real-World Filing Scenarios
The scenarios below show how the rules play out in practice. Every table has exactly two columns to keep the trade-off clear.
Scenario 1, A Private Equity REIT With Phantom Income
| Decision | Tax Outcome |
|---|---|
| Sponsor declares a $2.1M consent dividend before filing | Dividends-paid deduction lifted to satisfy 90% distribution test, no cash leaves the REIT |
| Sponsor skips the consent dividend | REIT taxable income left undistributed, 21% corporate tax owed plus 4% §4981 excise tax |
Scenario 2, A Mortgage REIT With a TRS Servicing Arm
| Decision | Tax Outcome |
|---|---|
| Servicing fees earned inside the TRS, REIT receives only mortgage interest | Mortgage interest is good 75% income, TRS pays 21% on its servicing income |
| Servicing fees earned inside the parent REIT directly | Servicing fees fail the 75% income test, REIT status at risk under §856(c)(3) |
Scenario 3, A Public Equity REIT With a Land Sale
| Decision | Tax Outcome |
|---|---|
| Land held over two years, six sales, basis sold under 10% cap | §857(b)(6)(C) safe harbor protects against 100% prohibited transactions tax |
| Land held only 18 months, twelve sales | Gain treated as dealer income, taxed at 100%, possibly fails 75% income test |
Three Named Examples That Walk the Form
David runs Magnolia Apartments REIT, a private equity REIT with 142 accredited investors. He files Form 1120-REIT every April, claims a $14.8 million dividends-paid deduction on Line 21b, and uses Schedule K Question 4 to confirm the 100-shareholder rule. His fund used a consent dividend in 2024 to absorb $1.6 million of phantom cancellation-of-debt income, which kept his 90% distribution test satisfied without a cash strain.
Priya manages Summit Mortgage REIT, a publicly traded mortgage REIT. She reports interest on Line 2, claims a §163(j) limitation on Schedule J because she did not elect out, and reports her TRS dividend on Line 1. Her 95% income test runs at 99.4% because most income is mortgage interest, but the 75% test runs at only 78% because some income is non-real-property securities interest.
Marcus operates Cedar Industrial REIT, a hybrid REIT. He elects out of §163(j) for his real property trade or business, so his depreciation runs under ADS for 40 years on commercial real property, per IRS Rev. Proc. 2019-08. He reports rent on Line 3, mortgage interest on Line 2, and discloses cross-collateralized loan terms on Schedule K to show the loans are secured by real property.
Mistakes To Avoid
- Misclassifying tenant services as rent. The negative outcome is failing the 75% income test, because impermissible tenant service income contaminates rent under Treas. Reg. §1.856-4.
- Forgetting quarterly asset tests. The negative outcome is automatic disqualification at quarter-end without a 30-day cure window.
- Skipping the dividend designation letter within 30 days of year-end. The negative outcome is shareholders losing capital gain rate treatment on capital gain dividends.
- Treating the §163(j) election as annual. The negative outcome is a permanent ADS depreciation method that the REIT cannot reverse later.
- Ignoring the 100-shareholder rule after year one. The negative outcome is termination of the REIT election under §856(a)(5).
- Running services directly instead of through a TRS. The negative outcome is impermissible tenant service income plus a 100% tax on that income under §857(b)(7).
- Under-distributing taxable income. The negative outcome is loss of the 90% test, regular corporate tax, and the 4% §4981 excise tax.
- Missing the prohibited transactions safe harbor. The negative outcome is a 100% tax on the entire gain under §857(b)(6).
- Filing Form 1120 instead of Form 1120-REIT. The negative outcome is the IRS treating the entity as a regular C-corporation, ignoring the dividends-paid deduction.
- Forgetting state REIT addbacks. The negative outcome is unpaid state tax in addback states like Illinois, New York, and North Carolina.
Dos and Don’ts
- Do reconcile Schedule L assets to your quarterly asset test workpapers, because the IRS will ask for them on exam.
- Do file Form 7004 even if you expect a refund, because it preserves administrative options.
- Do designate capital gain dividends in a written notice within 30 days of year-end, because shareholders cannot claim the rate without it.
- Do run all impermissible service income through a TRS, because the TRS structure is the only safe harbor for active services.
- Do document reasonable cause contemporaneously, because the §856(c)(6) cure requires it in writing.
- Don’t run hotel or healthcare operations directly, because operating income fails the 75% test.
- Don’t hold more than 20% of assets in TRS stock, because the asset test caps it.
- Don’t ignore Schedule M-3 if assets reach $10 million, because the IRS rejects M-1-only returns at that threshold.
- Don’t take rent based on net profits, because §856(d)(2)(A) disqualifies it.
- Don’t skip estimated tax on built-in gains, because §6655 penalties apply.
Pros and Cons of REIT Status
- Pro, full deduction for dividends paid eliminates corporate tax on distributed income, which is the entire reason to elect.
- Pro, §199A pass-through deduction allows non-corporate shareholders a 20% deduction on ordinary REIT dividends.
- Pro, capital gain dividends keep their character to shareholders, preserving the 20% long-term capital gains rate.
- Pro, foreign investors get FIRPTA relief on certain REIT distributions under §897(h).
- Pro, public REITs gain liquidity, broadening the investor base.
- Con, the 90% distribution test forces cash out, leaving little retained capital for reinvestment.
- Con, the qualification tests demand quarterly compliance work and ongoing legal cost.
- Con, prohibited transactions tax at 100% under §857(b)(6) blocks active development without a TRS.
- Con, state REIT addback statutes claw back the federal benefit in several states.
- Con, conversion from C-corp triggers a 5-year built-in gains period under §1374 by reference in §337(d) regulations.
Federal Process After You File
The IRS routes 1120-REIT returns through the Ogden submission processing center and matches them against Form 1099-DIV data, Form 8612 excise tax filings, and shareholder K-1-style information. Mismatches trigger CP2000 letters within 18 months.
The REIT must keep records for at least three years under IRC §6501, and six years if gross income is understated by 25% or more. The consequence of weak records during an exam is the IRS reconstructing income on its own terms, often unfavorably. A common misconception is that an electronic filing acknowledgment is the same as IRS acceptance; it is only acknowledgment of receipt.
State Tax Nuances and Addback Statutes
Most states tax REITs the same way the federal code does, allowing the dividends-paid deduction. Several states do not.
Illinois requires a captive REIT addback that disallows the dividends-paid deduction for REITs owned more than 50% by a single C-corp, under 35 ILCS 5/203. The consequence is full state corporate tax on the captive REIT’s income, defeating the structure. A common misconception is that all REITs are exempt under the Illinois Income Tax Act; only non-captive REITs get the federal flow-through.
New York and North Carolina have similar captive REIT rules under N.Y. Tax Law §209 and N.C. Gen. Stat. §105-130.7B. Real example: Atlas Captive REIT, owned 100% by a parent C-corp, lost most of its planned tax benefit when New York added back $9.4 million of dividends.
Texas has no income tax but imposes the Texas franchise tax, which applies to REITs at 0.375% or 0.75% of taxable margin depending on industry. The consequence of ignoring the Texas filing is a forfeited charter, which freezes property transfers.
Frequently Asked Questions
Is electronic filing required for Form 1120-REIT?
Yes. Any REIT filing 10 or more federal returns of any kind in a year must e-file under Treas. Reg. §301.6011-15, and most REITs cross that threshold from 1099-DIV alone.
Can a new REIT make a late election?
No. The election is made by timely filing the first 1120-REIT, with no separate late-election relief, although Form 7004 can extend the original due date by six months.
Does a REIT pay corporate tax on retained capital gains?
Yes. Retained capital gains are taxed at the entity level under §857(b)(3), and shareholders claim a credit through Form 2439 for taxes paid.
Are TRS dividends good income for the 75% test?
No. TRS dividends qualify for the 95% income test but not the 75% test, so most equity REITs limit TRS distributions and rely on rent for the 75% test under §856(c)(3).
Can a REIT skip a year of distributions?
No. The 90% distribution requirement runs every year, and a missed year triggers full corporate tax plus a 4% excise tax under §4981.
Is Form 1120-REIT used by foreign REITs?
No. Only domestic entities taxable as corporations file Form 1120-REIT, while foreign vehicles use Form 1120-F or treaty-specific forms.
Does Schedule M-3 replace Schedule M-1?
Yes. Once the REIT has $10 million or more of total assets, Schedule M-3 replaces Schedule M-1, providing detailed book-tax reconciliation.
Can a REIT carry back a net operating loss?
No. Post-2017 NOLs cannot be carried back and are limited to 80% of taxable income going forward under §172, with REIT-specific rules in §172(b)(1)(B).
Is the 4% excise tax avoidable?
Yes. Distributing at least 85% of ordinary income, 95% of capital gain net income, and 100% of any prior shortfall by year-end avoids the 4% §4981 excise tax.
Can a REIT own a partnership interest?
Yes. A REIT looks through the partnership for income and asset tests under Treas. Reg. §1.856-3(g), so partnership rents flow through as good rent at the REIT level.
Must a REIT file Form 8612?
Yes. Any REIT owing the 4% excise tax files Form 8612 by March 15 of the year after the tax year, separate from the 1120-REIT filing.
Are private REITs subject to the same rules as public REITs?
Yes. IRC §856 makes no distinction by listing status, so private REITs run the same income, asset, distribution, and shareholder tests as public REITs.
